An overhead valve engine, abbreviated (OHV) and sometimes called a pushrod engine, is a piston engine whose valves are located in the cylinder head above...

overhead valve engines (OHV), where the camshaft is located below the combustion chamber in the engine block. Single overhead camshaft (SOHC) engines...

produced in single overhead camshaft and dual overhead camshaft configurations until a V6 engine replaced it. The Nissan TB overhead valve engine was introduced...

poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve engine. Flatheads were widely used internationally...

an IOE engine, the intake valves were located directly above the cylinder (like the later overhead valve engines), however the exhaust valve remains...

Austin's marine engine of 1910 produced 300 bhp and was installed in a speedboat called "Irene I"; its all-aluminium, twin-overhead-valve engine had twin magnetos...

A multi-valve or multivalve engine is one where each cylinder has more than two valves (an intake, and an exhaust). A multi-valve engine has better breathing...

"pocket valve" being used for IOE engines. An F-head engine combines features from both overhead-valve and flathead type engines, the inlet valve operating...
